Lighting System Of Optical Fiber Transmission Solar

Solar energy is a clean energy and also a kind of potential fordevelopment, as renewable resources it has an incomparable advantagecompare with fossil energy. In recent years, the solar energy got more andmore attention from experts and scholars in various countries, but thesolar energy has obvious disadvantage——low utilization efficiency. Italso hinders the development of extensive use of solar energy. In order tofurther improve the utilization efficiency and extend range of the solarenergy utilize. So as to further improve the utilization efficiency and therange of application of the solar energy. This paper presents the fibersolar illumination system, it has simple structure,low cost and wideapplication range. It can be applied to subway, underground buildings andcannot accept light bedroom environment. And effectively play the roleof saving energy.The paper established a Fresnel lens spotlight model in advance, discusses the convergence properties of Fresnel lens. Calculation showsthat the Fresnel lens on the incident angle of the sunlight is very high, itoffers theoretical basis for design. Then paper analyzes the influence ofcoupling efficiency by angle error, axial error and longitudinal error.Calculations indicate that axial error and longitudinal error had greaterimpact and angle error was relatively small. According to the Fresnel lensand optical fiber coupling convergence characteristic designed of aspecial coupling device. And design of mechanical condenser platform,according to the technical requirements of optical system. Design ofthree-dimensional adjusting base, It could adjust the angle error and axialerror and longitudinal error. And make the design and calculations forworm gear and worm drive. Though the high precision mechanical deviceto ensure that the whole optical system design requirements.This system uses the computer as the controller, this paper designsthe interface control card and the core device of control card is chip of8254. Through the VC6.0programming platform control tracking controlsystem. Due to the optical path system of tracking precision is very high,Control systems increased the photoelectric sensor. The core device ofsensor is Four-quadrant silicon solar cell. By quadrant light batteryvoltage correction of the difference signal to adjust the tracking devicetrack, eventually achieve high precision tracking system.
